Impact of electric vechicles on power transmission grids.

This paper presents a methodology for assessing the impact of electric vehicles (EVs) on the power transmission grid of the Costa Rica Power System. The methodology considers penetration scenarios, user preferences, charging habits, and expected fleet growth. Using ETAP software, the study simulates power flow, demand behavior, and voltage levels in the presence of high penetration of electric vehicles. The analysis covers a 15-year horizon and focuses on voltage and demand profiles in 2025, 2030, and 2040. The results indicate a decline in voltage profiles that reaches dangerous levels after 2030, primarily in the distribution grid, and an increase in demand by Image 1 for 2040 in the most severe scenario. The analysis also reveals several key findings (a) the identification of problems in the electrical infrastructure starting in 2030 and a major insufficiency in accommodating the increase in EVs by 2040; (b) the need to evaluate stability in transmission grids considering loadability and voltage; (c) the necessity of investing in electrical infrastructure, driven by public policies, to meet future energy requirements and strengthen transmission networks; (d) the significance of accounting for both EV growth and electric infrastructure improvements in system analysis; and (e) the anticipation that the system's performance will fall within the extreme demand values presented in the analysis. The study emphasizes the importance of considering a broader range of scenarios and variability in parameters, especially user charging behaviors, to enable decision-makers to plan for the challenges and opportunities associated with the widespread adoption of EVs in a country's power grid.

O trabalho de Eros e de Tanatos na regulação social / The work of Eros and Thanatos in the social regulation

Este estudo objetiva discutir o trabalho de Eros e de Tanatos no contexto de regulação social na qual a responsabilidade social organizacional é comumente associada a um sistema de gestão capaz de minimizar os efeitos negativos do capitalismo. O trabalho de campo indicou uma falácia entre o discurso e as práticas da responsabilidade. Utilizaram-se dados qualitativos de três organizações, classificados com base na lógica das representações sociais. Identificou-se a responsabilidade social organizacional a serviço de Eros, enquanto possibilidade para vencer a angústia de morte organizacional. Mas este modelo também é vulnerável ao trabalho de Tanatos. Internamente, junto aos trabalhadores, se a RSO não recebe investimentos para ser uma ferramenta eficaz de oxigenação do sistema organizacional torna-se ela mesma parte de sua necrose. Conclui-se que a percepção do trabalho de morte que se instala na dinâmica institucional pode favorecer seu enfrentamento e criar saídas para a necrose do tecido social do qual as organizações também fazem parte.(AU)

This study aims to discuss the work of Eros and Thanatos in the context of social regulation, where the organizational social responsibility is commonly identified as being a management system capable of minimizing the negative effects of capitalism. The fieldwork indicated a fallacy between discourse and practices of responsibility. Qualitative data from three organizations were used and categorized based on the logic of social representations. It has been identified that the organizational social responsibility is in the service of Eros, being a possible way to beat the anguish of organizational death. However, that model is vulnerable to the work of Thanatos. It has been concluded that the perception of the work of death that is noticeable in the institutional dynamics may favor its confrontation and also find ways out to the necrosis in the social tissue which work organizations are also part.(AU)

Sistema automatizado de gestión de la maestría Informática en Salud / An automatized management system for the mastership in Healh Informatic

Se presenta la propuesta de un sistema para el control automatizado de la gestión de la Maestría Informática en Salud. El sistema permitirá coordinar actividades docentes y gestionar la información de estudiantes, profesores y graduados en aras de agilizar los procesos y obtener, de manera oportuna, la información necesaria a cada uno de ellos y a los directivos, para hacer un uso más eficiente y eficaz de los recursos. La propuesta del sistema se realizó a partir de las entrevistas efectuadas al personal relacionado con la actividad, y de la revisión documental correspondiente a cada una de las ediciones de la maestría, con vista a caracterizar el proceso y resumir los elementos de interés(AU)

We are presenting a system for the automatized management for the Mastership in Health Informatics. This system will permit to coordinate teaching activities and to manage the information about students, professors, and masters already graduated in the program in order to improve the process and get, on time, the necessary information, to make a better use of the resources. The proposition is based on the information obtained from interviews, and documents reviewed about each one of the eleven editions of this Mastership, in order to characterize the process and summarize the information we are interested in(AU)
